    usb: phy: generic: Get the vbus supply
    
    [ Upstream commit 03e607cbb2931374db1825f371e9c7f28526d3f4 ]
    
    While support for working with a vbus was added, the regulator was never
    actually gotten (despite what was documented). Fix this by actually
    getting the supply from the device tree.
